MACHINE FOR WINDING YARN OR THREAD.

SIEIilCIFICATION.forming` part of Letters Patent N'o. 276,758, dated May 1, 1883.

4 Appnaatinntlea october an, 1881. (No model.)

To all lwhom it may concern Beitknown that we,J OHNBOYD and THOMAS ALEXANDER BOYD, of Glasgow, in the county of Lanark,in the Kingdom of Great Britain and Ireland, have invented a new` and useful Improvement in Machines for Winding Yarn or Thread, of which the following is a specilication. Y

Our invention consists of certain improvements in the construction of machines for winding yarn or thread, in which it is desirable to stop the winding action ofthe machine when there is an excessive strain on the thread from its being entangled or other cause, so that the machine may be stopped before the thread breaks.

Our invention is also applicable to machines yarns, ropes, wires, ne., and to otheranald gous machines, and by it the action of these machines in whole or in part may be stopped.

The view in the accompanying drawing is a vertical section of a Winding and clearing machine embodying our invention, the same devices being shown in duplicate on opposite sides of the machine, so that a description of one set of devices will apply to both. The devices on the left-hand side of the figure are all` shown in operative position, while on the righthand side the bobbin or spool 1, on Vwhich the of the driving-drum 2 when thewinding action is stopped.

The winding devices illustrated in the drawing are similar to those shown in our United States Letters Patent No. 217,769, dated July mounted in bearings in the frame, and supporting on its upper peripheryduring the winding operation the bobbin 1, which is driven by frictional contact with the drum. This boboted to the frame and curved on its under side, so that by the movement of the hand-lever 33 the lever 3 may lift the bobbin out of or lower it into contact with the drum, as set forth in oui` patent. v

The thread or yarn, 4, to be wound onto the bobbin is shown in the drawing as being led from a hank, 5, carried on racers7 or reels 6, supported in brackets 7 on the fixed rails or beams 8 ofthe frame of the machine. Instead of being drawn of banks, the yarns or threads may be led from cops or -bobbins, and from the banks, cops, or bobbins they pass over rods 9, which may be provided with clearing-fingers 10,' adjustable to clear the threads of lumps and imperfections asthe threads pass between the n gers. The threads thence pass through traverse-guides 11, carried by thetraverse-bar 12, to which an intermittent reciprocating motion isimparted byanyof' the usualmcans. The threads, after passing through these guides, pass over rods 13 on pivoted levers 14, carrying the pivoted stopper-slips 17, to be introduced between the driving-drum and bobbin.

These stopper-levers are pivoted to the main transverse rail 15, and are provided with adjustablecounterbalanceweights 16, which can beset by means of screw-Shanks so as to properly counterbalauce threads 0r yarns ot' dierent strengths. A weak thread requires: only a slight counter-weight, while a strong thread may be wound with a much greater counterweight. Each counter-balance 16 so acts on its-lever 14 against the strain on the thread as to keep the said lever under ordinary conditions in contact with the stop-pin 3 on the armot' the bobbin-carrier 3, and the slip 17 held back from being interposed between the bobbin and its driving-drum, as shown at the left-hand side of the gure in the drawing.

In the stop-motion illustrated in our patent above cited the partswere so constructed that on the breaking of a thread the weight of the counter-balance would cause the stopper-slip to enter between the driving-drum and bobbin.f In our present machine the action is the opposite of this. The counter-weight tends to pull the slip back from the bobbin, and the slip is caused to enter between the pulley and bobbin only when an undue increase in the tension on the thread 4, arising'from the entangling of the thread in the hank or catching of a lump in the clearer 10, or other cause, overcomes the counter-weight 16 and pulls the lever 14 over. The stopper-slip 17 will thus be introduced between the driving-drum and bobbin, which together will pull it forwardl until the stopper-lever 14 comes in contact with a front stop-pin, 32, on one of the arms of the bobbin-carrier 3, as shown at the right-hand IOO side of the ligure in the drawing.v By this introduction of the slip 17 between thc drivingdrum and bobbin the winding action will be instantly stopped, and the stopper-slip will be held in its forward position by the friction of the driving-drum and the pressure ofthe bobbin.

As by the construction described the niachine is stopped before the thread breaks, it is not necessary for the operator to search for one end on the bobbin and the other on the bank to piece them, as must be the case where the thread breaks. The operator, having removed the obstruction from the entangled bank or thread caught in the clearer or other cause of stoppage, slightly raises the bobbin by means of the arms 3 and lever 33, so as to allow the stopper-lever 14 and its slip to fall back, and, the bobbin being now again lowered onto the drivingdrun1,tbe winding of the thrad is resumed.

We claim as our invention- 1. The combination of a driving-drum with a movable lever carrying a stopper-slip, and acted on by the thread or yarn as the latter passes to the bobbin, and provided with a balancing device to counteract the strain of the thread or yarn, whereby an undue increase of the strain on the latter will overcome the counter-strain on the stopper-lever, and introduce the slip between the bobbin being wound and the drum, which completes the stoppage of the bobbin, all substantially as set forth.

2. The combination of a driving-drum with a movable lever carrying a stopper-slip, and acted on by the thread or yarn as the latter passes tothe bobbin, and provided with a balancing device adjustable to counteract the strains of threads of different strengths, substantially as set forth.

3. The combination of a driving-drum with a pivoted `lever carrying a stopperslip, and acted ou at one end by the thread or yarn, and provided at the other with an adjustable counterbalancing device, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
